I was looking around at the cute spray achievements (
http://overwatch.wikia.com/wiki/Cute_spray) and decided to try to get Reinhardt's. It seems easy. All you need to do is hit an earthshatter, fire strike, and charge. I hardly ever play Reinhardt, but I've been playing him on quick play ever since the Uprising event started, since I realized he can be an interesting character to play.
But I can't seem to get the achievement. Earthshatter, firestrike alone is 150 points, so squishies who've taken just a little damage will die before you can even charge. So you have to hit more robust characters. But then you have to worry about your own teammates, who'll likely start shooting at the stunned opponents, killing them before your charge lands.
Then yesterday, I thought I finally had it. Roadhog was there. No shield. My teammates were far enough behind me that they probably wouldn't kill Roadhog before my charge hits. So I'm charging at him and what happens? Enemy Junkrat threw a mine at me, changing my direction.
Fine, I'll try again next round. Same thing happens, I have Roadhog in my sights. Ult. Fire strike! Charge!!
Boop. God damn Lucio!
